本文以协议的形式提出了一种新的以太网交换机集群管理方案，将二层交换机和三层交换机的集群管理无缝地结合在一起。

In this paper, a new cluster management system is described by proposing a new protocol, with this protocol layer 2 and layer 3 switches can be managed in a cluster system seamlessly.

例如，若某台多层交换机支持ip协议，ipx包则只能在第二层上交换，不能在第三层上规定路由。

For example, if a multilayer switch supports IP, then IPX packets can only be switched at layer 2 not routed at layer 3.
